it couldn't be that hard to wire around it, especially if you had a carburated vehicle.

Ditto...anyone with basic electrical experience can disable one. There are also ways to cheat them such as a can of compressed air or have someone else blow into it for you. If my new car came with one it would be the first mod I made...but then they will probably make it a felony punishable up to 50 years for tampering with one
